Specification of Letters Patent.

Patented Sept. 5, 1905.

Application filed May 3, 1905. Serial No. 258,638.

fr) 1./7 /w/mn: if' N14/...y colt/167%:

Be it known that I, YDAvID S. KENNEDY, ot' Brooklyn. county of Kings, and State otl New York,have invented a new and useful Improvement in Linotype-Machines, of which the following is a specification.

My invention has reference to improvements designed for use in Mergenthaler linotypemachines ot' the general organization represented in United States Letters Patent No. 436,532, and particularly to the improved form of said machines in which the magazine eon taining' thematrices is arranged to be removed laterally, as represented in application for I5 United States Letters Patent tiled by me on the 19th day ot' November, 1904, Serial No.

The aim ot' the invention is to prevent the removal of the magazine until the matrices are locked securely therein, and,on the other hand, to prevent the unlocking ot' the matrices until the magazine is in proper workingposition` Figure I is a perspective view of the upper part oi a magazine having my improvementincorporated therein, the magazine being partly withdrawn. Fig'. 9. is a perspective view of the upper left-hand corner ot' the magazine, together with the device t'or closing the same, and the adjacent portion of the main frame, the upper end of the magazine being closed and the magazine unlocked or withdrawn. Fig. 3 is a similar view of the parts with the upper end ot' the magazine opened and locked in place. Fig. 4t is a perspective view ot' the lower left-hand corner of the magazine locked in operative position, together with the adjacent parts. Fig. 5 is a perspective view ot' the same parts with the magazine unlocked preparatory to removal.

Referring to the drawings, A represents the upper portion ot' the main frame inclined rearward to give support to the magazine B and the distributing devices (l above the magazine and the escapement-lmr D at the lower end ot the magazine. The magazine receives Inatrices at its upper end `from the distributer and delivers them one at a time through the escapement-bar D to the vertically-channeled trent plate E, by which they are in turn delivered to the distributing devices.

The magazine B consists, as usual, of parallel top and bottom plates secured to intermediate spacing-pieces and grooved in their inner or opposing 'faces to receive and guide the upper and lower edges ot' the matrices M. The escapementbar l), lixed to the main frame, contains, as usual,ehannels corresponding to those otl the magazine and Vfor each channel an escapement device controlled through intermediate connections from linger-keys and adapted to discharge the matrices one at a time. as fully described in the application and patent above referred to.

rIhe magazine lying on top of the 'trame is provided with transverse guides or ribs on the under side to engage corresponding guides d on the main frame, this arrangement permitting the magazine to be drawn laterally from the machine in order that it may be replaced by another Acontaining matrices otl a diterent `font or tace, the construction in this regard being the same as in my application above referred to.

lVhen the magazine is detached from the machine, it is important that the matrices should be locked therein at both ends in order to prevent their accidental escape. For this purpose YI employ at the lower end of the magazine the transverse locking-bar H and at the upper end a pivoted lid or swinging cover I. The bar H, having a beveled inner end, is thrust through the magazine from one side and engages the upper shouldered edges ot' the matrices in such manner as to prevent their escape. In order to prevent the removal of the magazine prior to the insertion ot' this locking-bar, .I provide a gravitating latch F, (see Figs. ft and 5,) pivoted at f to the left side ot' the main frame A and adapted to engage at its upper end on a peripherally-notched stud (lr on the side of the magazine. lVhen the bar II is inserted, as shown in Fig. 5, its beveled inner end acts against the dog F and thrusts the same backward out otengagement with the stud G, leaving the magazine free to be withdrawn laterally. lVhen, on the contrary, the bar l'I is withdrawn to unlock the matrices, the latch F is permitted to t'all fora ward and lock the magazine in position. In this manner it will be seen that the removal ot' the magazine is prevented until the matrices have iirst been locked securely within its lower end.

W'hile I prefer to employ the devices herein i shown, it is to be understood that the essence i ot' the invention resides in the combination of IOO coacting means for locking the matrices within the magazine and for locking the magazine in place, and it will be manifest to the skilled mechanic that these parts may be widely varied in their arrangement without changing' essentially their functions or mode of action.

The closing or covering device I at the upper end of the magazine consists of a bar or plate of suitable width to cover and close the channels having its ends turned downward on the sides of the magazine and slotted to receive connecting-studs z' z, so that the cover may be turned down over the end of 'the magazine in the manner shown in Figs. l and 2 or turned upward, as shown in Fig. 3, to uncover the channels. On the left or inner end this cover has its end extended downward alongside of the magazine beyond the pivots a suiicient distance to engage or overlap the side of the main frame, as shown in Fig. 3, when the magazine is in operative position and the cover open.. I/Vhen, on the other hand, the cover is turned down, as shown in Fig. 2, to close the magazine, its end is disengaged from the frame, so that the magazine may be readily withdrawn. The essence of this part of the invention lies in having the cover or closing device engaged to lock the magazine against lateral movement so long as the magazine remains open at the end, and it is manifest that the form and arrangement of the cover may be modied at will, provided only it serves this purpose.

The part Z), Figs. 4L and 5, is one of the hooks attached to the side of the magazine for the purpose of suspending the same temporarily on the side of the main frame during its removal or application. It forms no part of the present invention.

K represents a stud screwed into the main frame and having an enlarged or flanged head in position to engage the left side of the magazine and limit the inward movement of the veaoov Having described my invention, what I claim isl. In a linotype-machine, a frame and a magazine removable therefrom at will, in combination with means for locking the magazine in operative position and means for locking matrices in the magazine, the second locking device adapted to unlock the irst.

2. In a linotype-machine, aframe and a magazine thereon removable laterally at will, in combination with means for locking matrices in the magazine at will, and means controlled thereby for locking the magazine in operative position.

3. In combination with the frame and the removable magazine, a latch F to hold the magazine in place, and a removable matrix-locking bar H, adapted to actuate the latch.

4. In combination with a sustaining-frame and a magazine removable at will, means for closing the upper end of the magazine, adapted to also lock the magazine in place.

5. In a linotype-machine,a sustaining-frame and a magazine removable at will therefrom, in combination with a matrix-retaining bar jointed to the magazine and engaging the frame to hold the magazine in place.

6. In alinotype-machine,asustaining-frame and a magazine removable at will therefrom, in combination with means for locking the matrices in both ends of the magazine, and cooperating parts to prevent the removal of the magazine unless both matrix-locking devices are in action.

7. In combination with a main frame and the channeled escapement-bar iixed therein, the laterally-removable magazine, and an adjustable stop to control its position and insure alinement of its channels with those of the escapement-bar.

In testimony whereol I hereunto set my hand, this 1st day `of May, 1905, in the presence of two attesting witnesses.
